Description

Technical Field

[0001] The utility model relates to the technical field of heating pipelines, in particular to a stress protection device for heating pipeline valves. Background Art

[0002] Heating refers to supplying heat indoors artificially to keep the indoor temperature at a certain level to create a suitable living or working condition. When heating, heat energy needs to be transported from heat sources such as boiler rooms, direct-fired engine rooms, and heating centers to the thermal inlets of buildings through heating pipelines. Multiple heating pipelines together form a heat supply network, and these pipelines are usually designed according to specific technical standards to ensure the effective and safe transmission of heat energy.

[0003] In the prior art, during the operation of the heating pipeline system, as an important control component, the valve bears a large thermal stress. Especially when the valve is frequently opened and closed and the temperature fluctuates violently, this thermal stress is even multiplied. The direct consequence is that the valve material is extremely prone to fatigue damage. Over time, this fatigue damage will gradually accumulate, leading to valve leakage, wear, and even failure. The occurrence of these situations not only affects the normal operation of the heating system but may also cause more serious safety problems. Therefore, this application provides a stress protection device for heating pipeline valves to meet the needs. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a stress protection device for heating pipeline valves to solve the problems that the frequent opening and closing of existing heating pipeline valves and the violent temperature fluctuations lead to a doubling of thermal stress, which easily causes the accumulation of fatigue damage of materials, resulting in leakage, wear, and failure, affecting the system operation and bringing serious safety hazards.

[0005] To solve the above-mentioned problems, the utility model is realized through the following technical solutions:

[0006] A stress protection device for heating pipeline valves includes: a pipeline main body; a buffer part disposed inside the pipeline main body, the buffer part including: a spherical support frame having two circular holes formed thereon, the two circular holes being in a cross shape; a buffer member installed inside the spherical support frame, the buffer member being in a corrugated shape, the buffer member including: a plurality of buffer plates, the buffer plates having notches formed thereon, and a plurality of through holes I formed on the buffer plates.

[0007] The through holes I are evenly distributed, and the buffer plates are vertically installed inside the spherical support frame.

[0008] The buffer part further includes: a rotating rod installed on the spherical support frame; a driving member installed on the rotating rod.

[0009] A valve is provided on the pipeline main body, and the buffer part is made of high-strength material; two protective sleeves are provided on the pipeline main body, and the two protective sleeves are respectively located on both sides of the valve.

[0010] A plurality of rubber pads are respectively installed at the four corners inside the protective sleeve. The rubber pads are in sealed contact with the pipeline main body, and a through hole two for cooperating with the pipeline main body is provided inside the protective sleeve.

[0011] Two protective plates are respectively installed at both ends of the protective sleeve. The protective plates are hermetically connected to the pipeline main body through sealing rings.

[0012] A support part is installed inside the pipeline main body. The support part includes: a cross support member installed inside the pipeline main body; a transverse support member installed inside the pipeline main body; a longitudinal support member installed inside the pipeline main body. The cross support member, the transverse support member and the longitudinal support member are all arc-shaped.

[0013] The utility model provides a stress protection device for a heating pipeline valve. Compared with the prior art, it has the following beneficial effects:

[0014] In the above solution, by providing a buffer part, when the water flow impact occurs, the buffer plate can effectively absorb and disperse this part of the stress, significantly reducing the pressure directly acting on the valve, converting the kinetic energy of the water flow into the elastic potential energy of the buffer plate, thereby protecting the stability and integrity of the valve. The corrugated design endows it with a certain elasticity, enabling it to expand and contract accordingly according to the pressure change of the water flow. This self-adaptive expansion and contraction ability further alleviates the influence of stress on the valve, ensuring the stable operation of the valve under various working conditions.

Specific embodiments

[0024] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the protection scope of the present utility model.

[0025] The following illustrates the implementation manners of the present utility model through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0026] Refer to Figure 1 One Figure 7 , a stress protection device for a heating pipeline valve, comprising: a pipe main body 1; a buffer part 3, arranged inside the pipe main body 1, the buffer part 3 comprising: a spherical support frame 303, two circular holes are formed on the spherical support frame 303, and the two circular holes are in a cross shape; a buffer member 304, installed inside the spherical support frame 303, the buffer member 304 is in a corrugated shape, the buffer member 304 comprising: a plurality of buffer plates 3041, notches 3042 are formed on the buffer plates 3041, and a plurality of first through holes 3043 are formed on the buffer plates 3041.

[0027] The spherical support frame 303 serves as the support structure of the entire buffer part 3. It provides a space for installing the buffer member 304. The spherical design can evenly distribute the pressure from different directions, thereby improving the overall compressive capacity and stability. The cross-shaped circular holes can adapt to different usage requirements and will not form blockage points, reducing the fluid resistance.

[0028] The main task of the buffer member 304 is to absorb external stresses on the pipeline, such as thermal expansion and contraction caused by temperature changes, through its own deformation, thereby reducing the direct impact on the valve 4. The corrugated design enables the buffer member 304 to have good elastic deformation ability, and it can absorb a large amount of stress without causing permanent deformation. In addition, the corrugated design can also help disperse the stress and avoid stress concentration at a single point.

[0029] The first through holes 3043 are evenly distributed, and the buffer plate 3041 is vertically installed within the spherical support frame 303.

[0030] Due to the even distribution of the first through holes 3043, the fluid can pass through the buffer plate 3041 more evenly, thereby reducing the occurrence of local turbulence and eddy currents, decreasing the resistance loss during fluid flow, improving the hydrodynamic efficiency of the system, and enabling the stress to be more evenly distributed on the buffer plate 3041, reducing the stress concentration phenomenon. This can prevent certain areas from deforming or being damaged due to excessive stress, and improve the durability of the overall structure.

[0031] The buffer portion 3 further includes: a rotating rod 302 installed on the spherical support frame 303; and a driving member 301 installed on the rotating rod 302.

[0032] Through the combination of the driving member 301 and the rotating rod 302, the buffer portion 3 can dynamically adjust the position or state of the buffer member 304 according to changes in conditions such as temperature and pressure inside the pipeline to achieve the best stress absorption effect. The driving member 301 is a structure such as a stepper motor. The driving member 301 can provide precise control to ensure that the buffer member 304 can maintain the best working state under different working conditions, improve the response speed and control accuracy of the system. The dynamic adjustment ability enables the device to adapt to various working conditions. Whether under high temperature or high pressure conditions, the performance can be optimized by adjusting the position of the buffer member 304, thereby protecting the valve 4 from damage.

[0033] A valve 4 is provided on the pipeline main body 1, and the buffer portion 3 is made of high-strength material; two protective sleeves 2 are provided on the pipeline main body 1, and the two protective sleeves 2 are respectively located on both sides of the valve 4.

[0034] The provision of the protective sleeves 2 can effectively prevent damage to the valve 4 caused by external factors such as accidental collisions, thereby ensuring the safe operation of the valve 4. The buffer portion 3 made of high-strength material can still maintain good performance under high temperature or high pressure environments, reducing the risk of the valve 4 failing due to excessive stress. Using a buffer portion 3 made of high-strength material can withstand more stress, thereby extending the service life of the entire system.

[0035] The rubber gasket 5 can greatly improve the sealing performance of the system and reduce the possibility of medium leakage, which is particularly important for heating pipelines as it involves the efficient utilization of energy and safety issues.

[0036] Multiple rubber gaskets 5 are respectively installed at the four corners inside the protective sleeve 2. The rubber gasket 5 is in sealing contact with the pipeline main body 1, and a through hole two 6 for cooperating with the pipeline main body 1 is arranged inside the protective sleeve 2.

[0037] The rubber gaskets 5 are installed at the four corners inside the protective sleeve 2, forming multi-point sealing, greatly improving the sealing reliability and preventing fluid from leaking at the interface.

[0038] The rubber gasket 5 is in close contact with the pipeline main body 1, which can effectively prevent fluid leakage and improve the overall sealing performance of the system.

[0039] The use of the rubber gasket 5 can significantly reduce the leakage risk caused by poor sealing at the joint. Especially in high-temperature and high-pressure environments, the good sealing performance of the rubber gasket 5 is particularly important. Moreover, the rubber material has good shock-absorbing characteristics, which can absorb the vibration generated during the fluid flow inside the pipeline and reduce the damage to the pipeline main body 1 and the valve 4 caused by vibration.

[0040] Two protective plates 7 are respectively installed at both ends of the protective sleeve 2. The protective plate 7 is hermetically connected to the pipeline main body 1 through a sealing ring 8.

[0041] The protective plate 7 is hermetically connected to the pipeline main body 1 through the sealing ring 8, forming a double-sealing effect, further improving the sealing performance of the system and ensuring that the fluid will not leak at the interface. The use of the sealing ring 8 ensures the close contact between the protective plate 7 and the pipeline main body 1, preventing any possible fluid leakage, which is particularly important for heating pipelines in high-temperature and high-pressure environments. The protective plate 7, as a physical barrier, can prevent external objects from directly contacting the pipeline main body 1 and internal components, reducing the potential damage to the valve 4 and the buffer part 3 caused by external factors.

[0042] The support part 9 is installed inside the pipeline main body 1. The support part 9 includes: a cross support member 903 installed inside the pipeline main body 1; a transverse support member 901 installed inside the pipeline main body 1; a longitudinal support member 902 installed inside the pipeline main body 1. The cross support member 903, the transverse support member 901, and the longitudinal support member 902 are all arc-shaped.

[0043] The arc-shaped design enables the support member to better adapt to the curved shape inside the pipeline, thereby evenly dispersing stress, reducing stress concentration points, improving the overall strength and durability of the pipeline, protecting the pipeline and its internal components. Through the combined action of the cross support member 903, the lateral support member 901, and the longitudinal support member 902, support can be provided in multiple directions, preventing the pipeline from deforming in high-temperature and high-pressure environments and ensuring that the geometric shape of the pipeline remains unchanged.

[0044] During use, ensure that all sealing rings 8 and rubber gaskets 5 are correctly installed and have good sealing performance. Start the heating system: Start the system according to the operating procedures of the heating system to ensure that the pipeline is filled with hot water or steam. Monitor the temperature and pressure changes inside the pipeline in real time through temperature sensors and pressure sensors. When thermal expansion and contraction are caused by temperature changes inside the pipeline, the buffer member 304 absorbs stress through the deformation of the corrugated structure, thereby reducing the direct impact on the valve 4. Adjust the position or state of the buffer member 304 through the rotating rod 302 and the driving member 301 to adapt to different working conditions. The rubber gasket 5 inside the protective sleeve 2 is in sealing contact with the pipeline body 1 to reduce vibration and leakage. The protective plate 7 is hermetically connected to the pipeline body 1 through the sealing ring 8 to further improve the sealing performance. Through the combined action of the cross support member 903, the lateral support member 901, and the longitudinal support member 902, the structural strength of the pipeline body 1 is enhanced, and the stress caused by temperature changes is reduced.
